In such a switch device, for example, when the knob N _RR is operated, the contact holder 40 ₂ slides in the holder case 41, and the elastic contact parts 68 b and 68 c of the movable contact 68 are individually fixed contact 48 a. , 48b. At this time, when there is a slight step between the individual fixed contacts 48a, 48b and the surface of the insulating substrate 44, the elastic contact portions 68b, 68c ride up or down the step. However, since the elastic contact portions 68b and 68c are formed to have different spring constants by changing the widths thereof, at least one of the elastic contact portions 68b and 68c does not vibrate. The sliding contact state can be maintained, and therefore chattering does not occur when switching between conduction and interruption.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the present invention described in the scope of claims for utility model registration. It is possible to make design changes.

For example, the present invention can be applied to a structure in which a metal piece is fixed to an insulating substrate 44 to form a fixed contact, and a plurality of wires having different diameters and a plurality of different spring constants are used. It is also possible to form elastic contact parts.
